Conception d'organes automobiles par optimisation topologique

Abstract : In car manufacturing, designing mechanical components of low mass is critical in order to save on raw materials and in order to produce cars that consume less fuel. However, it is also important that comfort (mainly acoustic aspects) and security requirements are satisfied. In such a context, the aim of topology optimization is to determine, at the beginning of engineering projects, the main features of a component. Existing commercial software cannot deal with all the constraints relevant to a vehicle project, in particular dynamical constraints. We propose in this thesis a methodology and a software solution which can take into account such specifications and namely those required by Renault. It combines the topology optimization method SIMP and the mathematical programming algorithm FSQP. We tested the potential of our method, firstly on a simplistic academic problem, and then on the design of an engine accessories support.
